ACCESSORIES
• VMF-SIT3 : VMF System thermostat
interface card Mandatory accessory on
the VED unit equipped with VMF-E0
or VMF-E1 thermostat. The VMF-SIT3
accessory sends back the control of the
three speeds to the fan coils.
•
SIT3 : Thermostat interface card Accessory
compulsory on VED units combined with
thermostats different from the VMF System
The SIT3 accessory sends back the control
of the three speeds to the fan coils.
• SIT5 :
Thermostat interface card Accessory
compulsory on the VED unit with up to
2 water valves, combined to the PXAE
control panel. The SIT5 accessory sends
back the control of the three speeds and
the valves to the fan coils.
ACCESSORIES MANDATORY FOR THE OPERATION:
VMF-SIT3 INTERFACE CARD DEDICATED TO THE VMF SERIES THERMOSTATS
Thermostat interface card dedicated to
the VMF thermostats
The VMF-SIT3 accessory sends back the
control of the three speeds to the fan
coils.
The VMF-SIT3 thermostat interface card
is dedicated to the fan coils with VMF E0/
E1 thermostats, except for the models in
which the absorption of the motor does
not exceed 0.7 A.
Each fan col must be interfaced with
the VMF-SIT3 card.
VMF-SIT3 is equipped with a 2A fuse to
protect the fan coil.
If the fan coil absorbs more than 2A
and up to 4A, the internal fuse must be
replaced with a 4A fuse, (supplied).
The VMF-SIT3 accessory can no longer be
used for absorptions over 4A.
SIT3 - SIT5 INTERFACE CARDS
SIT 3
Each fan coil fitted with SIT3 card
becomes a Slave and can be controlled
from a centralised control panel with
electromechanical selector or with SIT 5.
The accessory sends back the control of
the three speeds to the fan coils.
The electromechanical control panels
with just the speed control can be fit-
ted directly to the SIT 3 without the SIT
5 interface.
SIT 5
The SIT5 accessory, Master interface card,
is connected to the electronic control
panels with or without control of the
valves and/or the electric resistors.
The accessory sends back the control of
the three speeds to the fan coils.
The PXAE electronic control panels or
those with valve control must also be
interfaced with a SIT5 .
